Critically endangered Galapagos tortoises become first time parents at nearly 100 years old

A pair of critically endangered, nearly 100-year-old Galapagos tortoises at the Philadelphia Zoo have just become first-time parents.

In an announcement last week, the zoo said it is “overjoyed” at the arrival of the four hatchlings, a first in its more than 150-year history. The babies are the offspring of female Mommy and male Abrazzo, the zoo's two oldest residents.
